According to the characteristics of mathematics and the age of primary school students, we should set up game situations, put new knowledge into game activities, make students eager for new knowledge through games, make students' attention in a highly concentrated state, acquire knowledge through games and improve their interest in learning.

For example, in class training, organize a 60-second quiz game.

Prepare several groups of oral math questions, divide the class into several groups, and choose 3 students as representatives in each group.

Then the teacher asks questions, so that each group of students can answer first, and the winner is the one who scores more, or a small red flag is awarded for each correct answer, and the winner is the one who scores more.

In the game, students pay close attention and unconsciously learn a lot of useful knowledge, which effectively improves students' interest in learning.
